# JavaScript

Languine supports JavaScript/TypeScript localization files, perfect for modern web applications. This format handles both object literals and module exports, supporting nested structures and dynamic content.

## Setting Up

First, make sure you've got a languine.json config file in your project root. Here's an example:

```json
{
  "locale": {
    "source": "en",
    "targets": ["sv", "de", "fr"]
  },
  "files": {
    "js": {
      "include": ["src/locales/[locale].js"]
    }
  }
}
```

## Translating

With your config set, run:

```bash
npx languine@latest translate
```

When you run this command, Languine will:

- Load your source JavaScript files (e.g., src/locales/en.js)
- Detect any new or modified translation strings
- Generate translations for your target languages
- Create or update the target language files (e.g., src/locales/sv.js)
- Preserve module structure and exports
- Handle nested objects and arrays
- Maintain code formatting and comments
- Generate TypeScript types if enabled
